The Story
Plant Bio
Buddleia davidii, or butterfly bush, is a fast, arching deciduous shrub from China and Japan, reaching six to twelve feet where it is left unpruned. Long tapering panicles of small lilac to purple flowers, each with an orange throat, open from June through September and carry a honeyed scent. The narrow grey-green leaves are pale and felted underneath.
It self-seeds freely and is listed as a noxious weed in Oregon and a problem plant in several other states, spreading into riverbanks and cleared ground. Plant a seedless or low-fertility cultivar where that applies, and deadhead spent panicles before they set seed. Doing so also keeps the shrub flowering harder into autumn.

Planting
How to Grow
- Plant in spring in full sun and free-draining soil.
- Space at least six feet apart; this shrub fills its allowance quickly.
- Water through the first summer, then only in drought.
- Cut the whole plant back hard to a low framework each spring.
- Deadhead spent flower spikes through summer to limit seeding.
- Leave the top growth over winter in cold areas as frost protection.
Pro Tip
It flowers on new wood, so a hard spring cutback costs no bloom and buys a denser, better-proportioned shrub.
